Lighthouse's Best Practices audit checks a grab-bag of technical hygiene items — using HTTPS, avoiding deprecated APIs, having no browser console errors, correct image aspect ratios — that don't fit neatly into Performance or SEO but still reflect overall site quality.
Lighthouse Best Practices flags trust and security issues — mixed content, deprecated APIs, console errors, insecure resources. These quietly erode user trust and crawler confidence.
The Best Practices score, part of Google's Lighthouse auditing framework, evaluates your site against a genuinely broad collection of technical and security best practices beyond what any single, narrowly-focused check could capture — this composite score reflects your overall technical implementation quality across numerous individual factors simultaneously.
The genuine breadth of what this score encompasses means improving it typically requires addressing multiple specific, individual issues Lighthouse identifies during its evaluation — rather than a single fix, meaningful improvement here usually comes from systematically working through the specific issues the tool flags, many of which overlap with individual security and technical checks discussed elsewhere throughout this broader hardening work.
This score provides genuine value as a consolidated quality signal precisely because it aggregates numerous individual technical factors into a single, trackable metric — while the individual underlying checks each provide specific, actionable detail, this composite score offers a useful high-level view of your overall technical health trajectory over time.
Addressing the specific issues Lighthouse identifies for your site requires reviewing your actual, current Lighthouse report for the specific factors affecting your particular score — since this composite metric can be affected by various different underlying issues depending on your specific site's actual implementation, genuine improvement requires addressing your site's actual, specific flagged issues rather than generic, one-size-fits-all remediation.
Lighthouse Best Practices score is 95+.
